Two more bugs in osx 'look up in dictionary' behaviour

Similar to the problem mentioned here, that was fixed in build 2113, the same problem with the wrong word being highlighted/(looked-up in osx dictionary) when hovering the cursor over the word and pressing cmd+ctrl+D appears when in distraction free mode. 

A second issue is that the highlighting of the word doesn't respect the font style/size of the underlying text. This is particularly problematic when the font size is relatively large (but is annoying even at size 12).

 
How this looks in textedit:

I'm testing out ST2 for writing my LaTex documents and use this feature more than usual so apologies if this seems relatively pedantic.
